A parametric environmental life cycle assessment of newspaper making in Spain.

摘要: Most LCAs estimate environmental impacts for a specific situation (industry, sector or location) in generic way, without considering the characteristics of product service being evaluated. This paper outlines relevance use parameters and scenarios assessment daily newspaper multiple factors. The results different were compared with baseline reference scenario. Different specifications, sources raw materials, manufacturing technologies, energy mix, locations printing plant, distribution possibilities have been taken into account. unit processes amounts allocated each resource may vary depending on scenarios. Inventory data obtained directly from measured consumption plant located Gran Canaria (Spain) internal inventories indirectly information existing products. As functional units, both 1 kg printed 1 used. impact methodology ReCiPe has applied this study. Also endpoint indicators are shown as score (Pt) areas protection. For variations number copies, show that very high small runs. large runs, decrease between −14 −16% respect to final depends several variables including recycled fiber, papermaking technology used plant. airlifted newspapers, means an increase over 98% Climate Change if it is not same place distribution. electricity mix also geographical location significantly affects impacts, especially case isolated territory increments 12% interconnected systems. An should take account suppliers materials equipment, technology, all affect product. From analysis scenarios, low runs well pages weights produce greatest impacts. recyclable paper, shorter distance factories renewable considerably reduce generated.
